SHOW-CASE LIGHTING FIXTURE.

Application filed December 11, 1925. Serial No. 74,702.

My invention relates to show case lighting fixtures.

One of the objects of my invention is to provide a show case lighting fixture which can be readily installed and wired.

A further object of my invention is to provide such a fixture which will be simple and compact in construction and durable and eflicient in use.

A further object of my invention will appear from the description and claims.

In the drawings in which my invention is illustrated Figure 1 shows a sectional view through the upper front corner of a show case showing the end of the show case lighting fixture;

Fig. 2 is a view from the right of Fig. 1;

Fig. 3 is a section substantially on the line 33 of Fig. 8, parts being broken away;

Fig. t is a section on the line H of Fig. 3;

Fig. 5 is a section on the line 55 of Fig. 3;

Fig. 6 is a section on the line 66 of Fig. 3;

Fig. 7 is a section on the line 7-7 of Fig. 6; and

Fig. 8 is a section on the line 88 of Fig. 3.

Referring now to the-drawings in detail, the construction shown therein comprises an elongated sheet metal casing 10 positioned in the upper front cornerot the show case 11 and open on its lower inner side to permit the insertion of the lamps and to allow the necessary illumination of the articles in the show case, a pair of combined wiring base and contact members 12, one at each end of the elongated casing and located within the casing, an external wiring base 13 located at the end of the elongated casing 10 and provided with wiring'terminals for the connection of the feed wires and a detachable socket member 14 into which the lamp is in serted.

The inner surface of the casing may be a vided to cover the feed wires lying in the channels 22, and the binding terminals. A

.nipple or bushing 23 is provided to receive the insulating covering 24: of the feed wires and this nipple is secured to a metal plate 25 which is secured on the insulating base by means 01 screws 26/ The lower one of these screws 26 also serves to hold the insulating cover 21 'in place.

Each of the wiring base and contact devices mounted inside of the elongated casing comprises an insulating ase 27, suitably recessed to receive the yielding contact members 28 and the wiring terminals 29. Each one of the spring contact members 28, is electrically connected with one of the binding terminal members by means or a screw 30 which also serves to'hold the contact and *iring terminal in place on the insulating base. Each screw 30, is threaded into a of the spring contact.

with one of the binding plates 15, on the outside wiring base by means of a long screw 32 (Fig. 7 which also serves to hold the outside wiring base in position at the 'end of the casing. Each of the wiring terminals-0n the inside wiring base at one end of the easing is electrically connected with one of the binding terminals on the inside base at the other end of the casing by means, of a wire 33, (Fig. 3) the upper end of which is inserted and soldered in the loop portion 34:, of the binding terminal. An insulating cover ing the wiring terminals 29,-and closing the end of the casing. The cover 35 and cap 36 are held on the base 27, by means of screws 37, (Fig.

The detachable receptacle member lt, co1nrises an insulating base 38, lamp engaging contacts 39 and a0, and contact engaging blades il for engaging the spring, contacts 28 on the insulating base 27. These contact blades 41, are connected, respectively, with the shell and center lamp contacts 39 and 40, by means of screws 42.

The circuit is from one of the feed wires 20, through onev of the binding terminals 15, on the outside base, the screw 32, connecting the outside base with the inside base, the

Each of the two clamping plates 31, is electrically connected ill;

spring contact 28, contact blade 41,.screw 4E2, center contact 40, lamp, shell contact 89, screw 4-2, contact blade 41, spring contact 28, and screw 32 to the binding plate 15 for the other feed wire. The wires 33 lying in the upper portion of the elongated casing serve to carry current from the binding terminals 29 on the insulating base at one end to the binding terminals 29 to the insulating base at the other end.

VVhil'e I have shown but one form of my invention, it is to be understood that I do not desire to limit myself to this particular construction since many changes and modifications may be made therein without departure from the scope of the following claims.

I claim:

1. A show case lighting fixture comprising an elongated open-sided casing for extending alongside of the show case, two wiring base and contact devices, one secured in each end of each casing, conductor wires extending between and secured to said wiring bases, each wiring base having contacts thereon for quick detachable engagement with the contacts on a lamp receptacle member, a wiring base for the supply wires mounted outside said casing and in alignment therewith, and means for electrically connecting the wiring terminals on the outside wiring base with the wiring terminals on one of the inside wiring bases.

2. A show case lighting fixture comprising an elongated open-sided casing for extending alongside of the show case, two wiring base and contact devices, one secured in each end of each casing, conductor wires extendmg between and secured to sa d wirmg bases,

each wiring base having contacts thereon for quick detachable engagement with the contacts on a lamp receptacle member, a wiring base for the supply wires mounted outside said casing and in alignment therewith, and common means for electrically connecting the wire terminals on the outside wiring rase with the wiring terminals on one of the inside wiring bases, and for mechanically securing said outside wiring base in place at the end of the casing.

A show case lighting fixture contruc-' tion comprising an elongated open-sided casing for extending along the edge of the show case, a wiring base secured in said casing at one end thereof, a cap for said casing covering the end of the wiring base, wiring terminals mounted on said base on the side adjacent the cap, contact membersv having base portions mounted on the other side of the wiring base, a receptacle member provided with lamp engaging contacts'and having contact blades for quick detachable engagement with the contacts on the wiring base, a wiring base for the main teed wires'mounted outside the casing adjacent the cap and in line with the casing, binding plates on said out side wiring base on the side adjacentthe cap, and screws extending through the inside wiring base and threaded into said binding plate for securing said outside wiring base against the end of said casing, said screws being electrically connected with the wiring terminals and contacts on the inside wiring base.

In witness whereof, I have hereunto subscribed my name.
